EDWARD G. HAYNE, OF OTTAWA, ILLINOIS.

SOUND-CONVEYEB ARM.

To all whom it may concern: 7

Be it known that I, EDWARD G. HAYNE, a citizen of the United States, residin at Ottawa, in the county of-La Salle and tate of Illinois, have invented certain new and useful Improvements in, Sound-Conveyer Arms; and Ido'hreby declare the following to be afull," clear, and exact description of the invention, such as will enable others skilled the art to which it appertains to make and'use the same.

This invention relates to the class of phonograph's'and more particularly to a sound conveyer' arm.

lhe princ'palobject of the invention is the provision'of a sound conveyer arm embodying a supporting arm, anextension arm rotatably} and hingedly connected to the supportinggarm, and a reproducer carried by the extension arm, said extension adapted to be rotated to move the reproducer from a horizontal'to a vertical osition.

Another object of the lnvention is the provision of means for retaining the extension armlin a rotated position, whereby the reproducer will be held firmly in its respective position.

Another= object of the invention is the provision of means for retaining the extension in operative or inoperative position.

A further object of the invention is the provision of .;spri ng'pressed means adapted to preventthejextension arm from rotating when in an inoperative orraised position.

A still 'furtherfobject of the invention is the provision of an adjustable reproducer embodying means for su porting a steel needle point and means or supporting a sapphire'needle point, whereby the reproducer may be adjusted to be used to play Edison and 'Pathe disk records or it may be adjusted to play Victor or Columbia disk records.

A still further object of the invention is the provisionof an indicator arm mounted upon the rotable, sound'oonveyer arm and a apted to cooperate with a numbered index 2 1 is formed with the horizontally disposed mounted uponthe machine, said numbered index adapted 'to correspond with a numbered index carried by the disk record,

whereby any desired part of the music that Specification of Letters Patent.

is desired to be re 'roduced may be readily and quickly located.

With these and other objects in vat, as will appear as the description proceeds, the invention comprises the various novel 'features of construction, combination and arrangement of arts, as will be more fully described hereinafter and set forth with particularity in the appended claims.

Referring to the drawings,

Fig. 6 is a transverse section on the line 66 of Fig. 5. I

Fig. 7 is a detail fragmentary perspective view of one end of the extension arm.

Similar characters of reference are used to denote like parts throughout the accompanying drawings and the annexed specification.

Referring more particularly to the drawings the letter A indicates the sound conveyer arm which is shown to consist of a horizontally rotatable supporting arm 1, one end of whichis curved downwardly and provided with a bearing flange 2 that is rotatably mounted within a base 3 vsecured upon the top 4 of the phonograph. The flange 2 is provided with a lug 5 that moves in a slot 6 formed in the vertical wall of the base 3 and is adapted to limit the horizontal rotating movement of the supporting arm.

The forward end of the supporting arm tubular barrel 7, in which is rotatably mounted a hinge pin 8 the outer ends of which are flush with the ends of the tubular barrel 7. The hinge pin 8 is provided adjacent one end with an annular groove 9 adapted to receive a set screw 10 that extends through the barrel 7 whereby the hinge pin is held within the barrel.

A tubular extension arm 11 has one end rotatably mounted within a bore 12 that extends through the hinge pin 8 at a point intermediate its ends. Extending centrally through one end of the hinge pin 8 is a set screw 13, which is provided with a threaded shank l4 and a reduced extension pin 15, that extends inwardly of the hinge pin and through an arcuate slot 16 formed in the end of the extension arm 11. This arcuate slot 16 extends substantially half way around the circumference of the extension arm and is adapted to limit the rotating movement of the extension arm to a half turn. Positioned upon the reduced extension 15 between the threaded shank 14 and the end of the extension arm 11, is a coil expansion spring 17 that is adapted to exert a sufficient amount of pressure upon the end of the extension arm to prevent the latter from rotating when it is in a raised or inoperative position.

The end of the extension arm 11 is also provided with a pair of depressions 18 that are adapted to be selectively engaged by a locking pin 19 carried by the outer end of a spring arm 20, which is positioned below the tubular barrel 7 and has its terminal end secured to the bottom of the supporting arm 1. The locking pin 19 is also designed to selectively engage through recesses 21 formed in the lower portion of the hinge pin 8, to hold the hinge pin 8 at the limit of its rotation in either direction. As clearly shown in Fig. 5 of the drawings the tubular barrel 7 is provided with a circumferential slot 22 through which the end of the extension arm passes for movement therein, the opposite ends of the slot serving to limit the vertical movement of the extension arm 11. As shown the forward end of the spring arm 20 extends well under the tubular barrel 7 into engagement with the lower portion of the extension arm 11 and is adapted to form a substantial resilient support for the exten sion arm 11. Should the extension arm 11 accidentally fall from an inoperative to an operative position, the force of the fall of the arm would be broken by the arm coming into engagement with the outer free end of the spring arm, and this would serve as a means to prevent the records becoming broken by the needle point of the transmitter dropping suddenly thereon.

The outer end ofthe extension arm 11 is provided with a right angular extension 23 upon which is mounted a reproducer 24, which is of ordinary and well known construction, therefore it is not thought necessary to give an extended description thereof.

rea -34a The reproducer carries the ordinary steel needle supporting device 25, which is shown to embody the usual form of needle socket 26. In lieu of the ordi'. ary set screw that extends through the socket 26 to clamp the needles therein, I employ a set screw which is formed with a sapphire needle point 27 on the head thereof, whereby the sapphire needle point 27 may be used to clamp the steel needles in position when it is desired to play Victor or Columbia records, or may be used to reproduce the music from Edison or Path records, which latter ordinarily use a sapphire or diamond needle point with their reproducers.

In order to play or reproduce music from Victor or Columbia disk records, the extension arm carrying the reproducer is arranged in the position shown in Fig. 2 of the drawings, wherein it will be seen, and more particularly by reference to Fig. 5, that the locking pin 19 engages through one of the recesses 21 and in one of the depressions 18 of the extension arm 1.1, so as to hold the hinge pin 8 against rotary move ment and also to prevent horizontal rotary movement of the extension arm 11. When it is desired to change the steel needle point carried by the reproducer, it is only necessary to grasp the extension arm and move the same upwardly to the position shown by dotted lines, and in so doing the hinge pin 8 will be rotated, which will cause the locking pin 19 to leave the depression 18 and ride up the inclined wall of and out of the recess 21, the locking pin 19 subsequently dropping into the other recess 21 in order to hold the extension arm 11 in its raised or inoperative position. 'Since the extension arm has been raised and therefore the locking pin 19 disengaged from one of the depressions 18, the expansible spring 17 carried by the set screw 13 will exert a sufficient amount of tension against the extension arm to prevent the latter from rotating, or in other words to prevent the reproducer from swinging from a vertical position to a horizontal position.

When it is desired to reproduce the music from Edison or Pathe records, where it is necessary to use a sapphire or diamond needle point, it is only necessary to grasp the reproducer and rotate the latter when in a raised or inoperative position so as to dispose it in a horizontal position, after which it may be readily and freely lowered into an operative position, as shown in Fig. 4 of the drawings, and when insuch position the locking'pin 19 will again engage the forward recess 21 of the hinge pin 8 and the other depression 18 of the extension arm 11 and positively and securely retain the extension arm in an operative position against movement.

From the foregoing it will be seen that by the construction described my improved neat sound conveyer arm and reproducer carried thereby may be used to play Edlson and Pathe records or Victor and Columbia d sk records, without the necessity of changing any of the parts.

In order to indicate and locate the particular part of the music which the repro ducer is reproducing, I employ an indicator arm 28 which has one end threadedly connected to the upright portion 29 of the supporting arm 1, while the other end of the indicator arm extends radially and is pro vided with an indicator hand 30 that is adapted to cooperate with a numbered index 31 that is carried by the phonograph machine. Each disk record is to have a numbered index to correspond to the numbered index 81 carried by the machine, and it is to be understood that this index may be printed directly upon the disk record or may be printed upon a paper sticker and attached to the record. From this it will be seen that as the needle point reduces the various parts of the music, that the indicator arm will move over the index, whereby the particular part of the music being played may be readily and quickly located at sight. Therefore, if it is desired say for instance, to reproduce the chorus the indicator arm may be moved back to the number on the index indicating the number corresponding to the number of the beginning of the chorus of the piece that may be upon the record, and

in like manner any particular part of the I 53 piece may be located immediately for reproduction.
